According to cell fractionation analysis, most actin is structurebound. Immunofluorescence shows signal enriched in the cell cortex, notably around ciliary basal bodies (identified by anti-centrin antibodies), as well as around the oral cavity, at the cytoproct and in association with vacuoles (phagosomes) up to several μm in size. Subtle strands run throughout the cell body. Postembedding immunogold labeling/EM analysis shows that actin in the cell cortex emanates, together with the infraciliary lattice, from basal bodies to around trichocyst tips. Label was also enriched around vacuoles and vesicles of different size including discoidal vesicles that serve the formation of new phagosomes. By all methods used, we show actin in cilia. Although none of the structurally welldefined filament systems in Paramecium are exclusively formed by actin, actin does display some ordered, though not very conspicuous, arrays throughout the cell. F-actin may somehow serve vesicle trafficking and as a cytoplasmic scaffold. This is particularly supported by the postembedding/EM labeling analysis we used, which would hardly allow for any largescale redistribution during preparation.</dcterms:abstract> <dcterms:rights rdf:resource=""/> <dc:creator>Plattner, Helmut</dc:creator> <dc:creator>Wagner, Erika</dc:creator> <dcterms:bibliographicCitation>First publ. in: Journal of Histochemistry and Cytochemistry 52 (2004), 12, pp. 1543-1559</dcterms:bibliographicCitation> <dspace:hasBitstream rdf:resource=""/> <dc:creator>Sehring, Ivonne Margarete</dc:creator> <dc:language>eng</dc:language> <dc:format>application/pdf</dc:format> <dspace:isPartOfCollection rdf:resource=""/> <dc:rights>Attribution-NonCommercial-NoDerivs 2.0 Generic</dc:rights> <dcterms:available rdf:datatype="">2011-03-24T17:34:29Z</dcterms:available> <dc:contributor>Plattner, Helmut</dc:contributor> <dc:creator>Kissmehl, Roland</dc:creator> <dc:contributor>Wagner, Erika</dc:contributor> <dc:contributor>Kissmehl, Roland</dc:contributor> <dcterms:hasPart rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:isPartOf rdf:resource=""/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Sehring, Ivonne Margarete</dc:contributor> </rdf:Description> </rdf:RDF>
